You can get the time management (plus minigames) game Megaplex Madness for 99 cents from BigfishGames by using the code mega99. After choosing to buy it, there is a place to enter this code which will take $6 off the standard $6.99 price.
Also, click the red x next to the line that adds their game club to your order. This will keep you from having to cancel it later or being billed $6.99 each month as a club member (for which you get a game each month and some other stuff).
